Abstract:
The International Atomic Energy Agency (IAEA) was formed in 1957 to promote the peaceful use of nuclear energy and to inspect civilian nuclear materials and activities to deter military diversions. To decide the frequency of inspections and inspection criteria, the IAEA set its safeguard standards with the objective of assuring “timely detection of diversion of significant quantities of nuclear material from peaceful nuclear activities to the manufacture of nuclear weapons.” The two nuclear weapon designs developed and detonated during World War II were the “gun-type” and “implosion” designs. Because implosion device technology requires much less fissile material than guntype technology, the IAEA significant quantity6 (SQ) values were determined based on the fissile material requirements of nuclear implosion devices like the plutonium-based “Fat Man” detonated over Nagasaki in 1945. Utilizing implosion designs perfected in the late 1940s, however, the explosive yields achieved in 1945 can be produced with much less fissile material. Table 1 lists the fissile material requirements of contemporary nuclear weapon technology. “Low Technical Capability” in Table 1 refers to the Mark III implosion device set off at Nagasaki. “Medium Technical Capability” refers to implosion designs perfected in the late 1940s and “High Technical Capability” in Table 1 refers to the implosion technologies the United States perfected in the 1950s.

Abstract:
The April 2 announcement in Lausanne of a framework for an agreement on the Iranian nuclear program has raised profound hopes and fears for the future of the Middle East. There are few developments with greater potential for fundamentally altering the political dynamics of the region – a prospect that fills skeptics with as much dread as it fuels optimism among supporters. To explore the many ramifications of the potential deal, the Project on Middle East Political Science convened a virtual symposium for the Monkey Cage. These essays have now been collected into an edition of the POMEPS Studies series, available for free download. The American public debate about the deal over the last month has primarily focused upon U.S. policy options and the details of the proposed agreement. The essays in this collection delve into such issues in depth: Michael Brown and Chantal de Jonge Oudraat explain why no better deal is on the table; Joshua Rovner explains why it matters that U.S. intelligence got Iran’s nuclear program right; Nick Miller and Or Rabinowitz show how the deal is in line with traditional U.S. nonproliferation policy; Steven Kull and Shibley Telhami investigate American public opinion toward a deal; Thomas Doyle explores the symbolic dimensions of the negotiations; and Austin Long argues that the deal limits Iranian options and will test Iran’s intentions in ways that even hawks should appreciate. Iran’s domestic politics have generally received less attention. The essays collected here offer an exceptionally nuanced profile of the issues and actors in play in the Iranian political system. The sheer extent and nature of the domestic debate over the deal is notable in its own right, as Mohammad Ayatollahi Tabaar explains in detail. Iranian debates have not broken down along traditional lines of moderates and hard-liners, as Shervin Malakzadeh carefully observes, but rather reflect a more fluid and fragmented factional array. Mohammad Ali Kadivar and Ali Honari trace the willingness of Iranian President Hassan Rouhani to negotiate to the legacies of the grass-roots movements that followed the contentious 2009 presidential election. As Farzan Sabet observes, Iran’s conservatives are divided internally and struggling to find the right tone amidst the new realities. Iran’s parliament, facing competitive elections, carefully tracks with the trends in public opinion. Iran’s nuclear scientists themselves represent a potentially important constituency, especially if the deal is ultimately operationalized. Meanwhile, Supreme Leader Ali Khamenei seeks to hedge bets and keep a delicate balance among the factions, with an eye towards sanctions relief – which itself, as Kevan Harris argues, would intersect in complex ways with the Iranian political economy that sanctions have molded.
